To all whom, it may concern: I

Be it known that I, WILLIAM KERsHAW, a subject of the Queen of GreatBritain and Ireland, residing at Leeds, in the county of York, England,have invented-a certain new and useful Improvement in Apparatus forFeeding Sheets of Paper and Similar Material to Printing, Ruling,Oalendering, and the Like Machines, of which the following is aspecification.

The object of this my invention is to feed sheets of paper and similarmaterial, hereinafter for the sake of brevity referred to as paper,singly sheet by sheet from a pile of sheets to printing, ruling,calendering, and the like machines, hereinafter similarly referred to asprinting-machines.

My invention attains the above end by offecting a partial separation ofthe topmost sheet of the pile at the rear end that is, at the endfarthest from the printing-machine while the forward movement of thetopmost sheet to complete its separation is effected by drawing forwardthe sheet from its front end, and also so that the sheets are moved orfedforward through the feed-rollers ina fannedout or overlapping manner.The object of drawing the sheet forward in place of pushing it forwardis to avoid the liability or risk, which more particularly exists withthin and very flexible descriptions of paper, of the bending or bucklingof the sheet, which often results in the sheets being twisted sidewiseor in two sheets being fed forward together. The object of feeding thesheets in a fanned out or overlapping manner is to reduce thespeed ofthe forward movement of the sheets, since during each revolution of theprintingcylinder they then require to move only a fraction of the totaldistance from the pile to the printing-cylinder. Otherwise the fulldistance has to be moved at each revolution of the printing-machine.

By my invention I efiect a combination of the pulling forward of thetopmost of the unseparated sheets and the fanned-out or overlappingmanner of carrying forward the sheets by causing the pulling-forwarddevice to enter at the back beneath the last or bot tom of thepartially-separated and fannedout sheets and above the topmost of theundisturbed sheets and to move forward above Figs. 1 to 3. part of Fig.3, showing the inner side of the Serial Nb. 701,380. on model.)

and out of contact with the topmost of'the undisturbed sheets until itapproaches the forward end of the sheet, when the pullinglatter part ofthe backward and the first part of the forward movement of the pullingdevlce.

Like the majority of feeding apparatus, my

invention comprises means for bending or buckling up the corners of thetopmost of the undisturbed sheets, means for holding down the cornersand back of the next sheet thus Iexposed, means for drawing forward thetop sheet of the pile and carrying it up to the printing-cylinder, and,lastly, means for antomatically raising the table as the height orthickness of the pile diminishes, all arranged to operate at the propertimes and adjustable to suit various sizes of sheets. These means,

constituting a feeder for printing-machines,

are illustrated in the accompanyingdrawings, in which Figure 1 is anoutside elevation of the lefthand side of the feeder. Fig. 2 is anoutside elevation of the right-hand side of the feeder, the terms rightand left hand referring to'a position at the back of the machine.

Fig. 12 represents a detail view of the said part alone, the same beingshown as in Fig. 10.

a are the side frames of the machine.

1) is the main driving-shaft, driven by any convenient means at the samespeed as the vertical side rods 9 and two short vertical side rods h, towhich the horizontal side rods 2' are attached at the back end bypin-joints j and at the front end by socket-joints 7;.

These are all raised and lowered together by the cams Z on the maindriving-shaft b and the cams m, acting on the under side of thecam-blocks n, secured toward the front end of the horizontal side rods1'. The cams on are secured on the rocking shaft 19, which is rocked bymeans of the lever (1, connectingrod 0', and crank-pin s, secured in theWheel t, which latter gears with the wheel a on the end of the maindriving-shaft b.

11 (see Figs. 3, 4, and 6) is a cross-bar the ends of which are securedto the adjustable sliding blocks 10, fitted capable of being slid on thehorizontal side rods 1', so that the crossbar 1; may be adjusted overthe back edge of the pile of sheets (Z. Two sliding blocks 00, Figs. 3and 4, are fitted on the cross-bar o in an adjustable manner, so thatthey can be adjusted with the depending presscr-feet z of the blocks or:immediately over the back corners of the pile of paper (I. A double arm1 is freely hinged to the upperpart of the foot ,2 and carries at itslonger end a rubber-covcred roller 2-, on which rests the end of a fiatspring 3 for the purpose of giving the necessary pressure on the paperand to prevent rotation of the roller 2. The spring 3 is attached to ahinged block 4, so that by means of the set-screw 5 the pressure of thespring on the roller 2 can be regulated. To the opposite end of the armis attached the vertical rod 6, the depression of which raises theroller 2 from the paper, and when raised sufficiently high the weightedcatch 7, hinged between the double arm 1, catches in the notch S of thepresser-foot and holds the roller 2 out of the way when a fresh pile ofpaper is being put into position. )Vhen the crossbar o is in the raisedposition, the double arm 1 hangs down nearer the vertical position, thethen position of the roller 2 being indicated by the dotted circle 2.(See Fig. 4.) As the cross-bar o descends the roller 2 is. pushed towardthe center of the pile of paper, buckling up the topmost sheet S, asindicated in Fig. 4, and laying bare the corner of'the next sheet Sbelow, and at the same time the presser-foot z descends onto the exposedcorner ofthe sheet S and holds this sheet fast during theimmediately-following drawingforward of the top sheet S. Before the endof the downward movement of the cross-bar 1), however, the lower end ofthe catch 7 reaches the top of the sheet S and acts both as a fulcrum totilt up the long side of the double arm 1, raising the roller 2 from thetop of the sheet S, which might disturb the subsequent pulling forwardof this sheet, and also as a stop to prevent the corner of thebuckled-up sheet Sslipping back beneath the presser-foot 5 before thisreaches the sheet S as the pressure of the roller 2 is being taken offthe sheet S.

The mechanism for drawing forward the top sheet is as follows:

Two main side levers 1O 11 are pivoted at 12 on the outside to the sideframes a and are rocked by means of connecting-rods 13- from crank-pins14, secured in the wheels to on the ends of the main driving-shaft I).These side levers are formed in two parts 10 and 11, which are hingedtogether at 15, the object being to automatically adjust the stroke ofthe upper end of the levers to suit the position of the back edge of thepile of paper.

In the upper part of the side frames at two horizontal slide or guideraces 16 are formed, having a widened and dropped portion at the frontend toward the feed-rollers. Sliding carriers 17 are fitted in theseraces 16 and connected to the upper ends 11 of the side levers by meansof a pin 18, secured in the back plate 19 of the sliding carrier17. Thepin 18 projects through the slot 20, formed in the upper end 11 ofthemain side lever. Stopbrackets 21, cast on or secured to the adjustablesliding blocks w, limit the backward motion of the sliding carriers 17to suit the position of the back edge of the pile of paper,

the hinged joint 15 0f the side levers permit ting the connecting-rods13 to follow the crank-pins 14c to the full extent of their backwardmovement. A strong flat spring 22 keeps the two parts 10 and 11 of theside levers in line at other times, being sufficiently strong toovercome the friction and inertia of the sliding carriers 17 in theslide-races 16.

The sliding carriers 17 carry between them a rubber-covered roller orbar 23, (see Figs. 3 and 5,) which extends across over the pile of paperand is provided at one end with a small ratchet-wheel 24.. (See Fig. 5.)A catch 25, loosely hinged to the back plate 19 ofthe sliding carriers17, permits the roller 23 to rotate as it is drawn back with the slidingcarriers 17, but prevents its rotation during the forward movement. Thisroller 23 moves forward above and out of contact with the topmost of theundisturbed sheets S of Fig. 4 until the sliding carriers 17 reach thedropped part of the races 16, when the roller 23 comes to rest on saidsheet and causes it to partake of its forward movement, whereby thefront edge of said sheet is fed into the grip of the feeding-rollers c.

The feeding-rollers e are geared together by means of toothed wheelsjust inside the righthand side frame and are rotated by means of thetoothed wheel 26, Fig. 2, on the end of the top roller-shaft, toothedwheel 27 engaging with toothed wheel 26, ratchet-pins 28, securedbetween the face of the wheel 26, and a pin-plate 29 on the stud 30,carrying the wheel 27, a hook catch-rod 31, reciprocated from acrank-pin 32, attached to the wheel 33, which is geared with the wheelit on the end of the driving-shaft b. The feedrollers e deliver thesheets to the carryingtapes f, Fig. 3, which carry the sheets forward upto the impression-cylinder of the printing machine.

In order to keep down the carrying speed, the above gearing is soproportioned that a sheet is carried forward only a short distance byeach intermittent movement of the feedrollers, so that the sheets arepassed through and from the feed-rollers in a fanned-out or overlappingmanner, as shown in Fig. 3. The first forward movement of each sheet,therefore, does not carry it past the pile, but leaves it in most casescovering more than half the sheet next below. It is necessary,therefore, to make provision for the passing of the drawing-forwardroller or bar 23 beneath it in order to allow the roller 23 at the endof its next forward movement to act upon the next succeeding sheet. Toeffect this, a triangular-shaped lifter 34 (see Figs. 3, 5, and 6) isattached to a light rod 35, hinged at the ends in two plates 36, whichlatter are hinged on the cross-bar 37, carried by and between thesliding carriers 17. The plates 36 rest upon the top of the roller 23,and the front edge or apex of the lifter 34 rests directly on the topsheet or is carried by a steel strip 38, soldered on the upper side, thefront end of which rests on the sheet. The lifter 34 is formed of verythin sheet metal, stiffened toward the front edge by wire 39. Theforward movement of each sheet is always more than sufficient to bringthe back edge of said sheet past the apex of the lifter 34 or the end ofthe strip 38-when the sliding carriers 17 are in their rearmostposition. On the next forward movement of the sliding carriers 17 thestrip 38 or the apex of the lifter 34 slides on the topmost of theundisturbed sheets, and on reaching the back edge of the last of thesheets moved forward it enters beneath the same and gradually lifts thisand the overlying sheets up above the drawing-forward roller 23 as itmoves forward.

A further provision for preventing any disturbance of the sheets belowby the drawing forward of the top sheet consists of a holder 40, securedto the upper end of a vertical rod 41, sliding between guide-bars 42,hinged on the main shaft Z). The rod 41 is raised by the cam 43 on theshaft 1) and depressed by the spring 44 at the proper times. The objectof hinging the guide-bars 42 is to enable them to be tilted back whenafresh pile of paper has to be inserted. To accommodate the rise andfallof the table 0, the bars 42 are fitted in a metal-faced recess inthe center of the back edge of the table 0, said recess being opened orclosed by tilting back or tilting down the hinged plate 45. The bars 42are also carried below the shaft Z) and the lower end locked by a lever46, hinged to one side frame at 47 and extending across to the oppositeframe for the purpose of steadying the bars 42 in a vertical position.The lever 46 is dropped to permit the lower ends of bars 42 toswinginward when a fresh pile of paper is to be put on the table.

The means for automatically raising the table consists of four verticalscrews 48, actuated by the following mechanism: On one end of the shaft49, extending from side to side across the machine, is fitted theratchet-plate 50, which is intermittently rotated by means of thecatch-pin 51 and catch-lever 52, hinged to the side lever 10.Longitudinal shafts 53 and bevel-gear 54 connect the four verticalscrews 48 to the cross-shaft 49. An L-shaped lever 55, hinged at 56,Fig. 1, extends over the top of the side frame a horizontally inward tothe center of the machine, near the top edge of the front board 57, andcarries at this end a feeler 58, which drops upon the top of the sheetswhen the sliding carriers 17 are at the rear portion of their stroke.The lower end of the vertical arm of the lever 55 enters an opening in ahorizontal web 59, cast on the loosely-hinged cam-lever 60. Thecam-lever is fitted loosely on its pivot-stud 61, so that the endnearest the lever 55 can move slightly inward when pressed by the end ofthe lever 55. A spring-button 62 tends to force the cam-lever 60 outwardas it is tilted upward past it by the end of the catch-lever 52 bearingagainst the under side of the web 59. \Vhen rotating the ratchet-plate50, the catchlever 52 rides upon a circular boss 63 behind theratchet-plate. 64 is a fiat spring to press down the can1-lever 60 onthe back stroke of the catch-lever 52 and acts on the upper side of theweb 59. A belly-shaped cam 65,formed on the outside of the cam-lever 60and, immediately beneath the web 59, tends to force the catch-lever 51outward, so that the catchpin 51 comes in line with the ratchet-plate50, while the flat spring 70 tends to press the catch-lever 52 inward,so that the catch-pin 51 passes inside, behind, and out of contact withthe ratchet-plate 50. \Vhen the top of the pile is sufficiently high orthe table is raised to the top, the pile being exhausted the feeler 58cannot drop as far as it otherwise would, so that the lower end of thelever 55 presses or holds the cam-lever 6O inward and keeps thebelly-cam 65 sufficiently far back to prevent it forcing the end of thelever 52 outward, so that the action of the flat spring keepsthe lever52 and the catchpin 51 inward and the latter out of contact ICC IIO

with the ratchet-plate 50, preventing any rotation of the latter, whichwould rotate the screws 48, to lift the table 0. Then the height of thepile is reduced sufficiently by removal of sheets, the feeler 58descends so far that the lower end of the lever 55 presses or holds thecam-lever 60 outward and brings the belly-cam so far forward that thelatter forces the end of the catch-lever 52 as the end of the same movesforward past the cam outward, bringing the catch-pin 51 into engagementwith the ratchet-plate 50, which is thereby partially rotated, causing aslight rotation of the screws 48 and a slight rise of the table 0. p

The mode of operating with the feeder is as follows: The lever 46 isdropped and the hinge-plate 45 thrown back, allowing the holder 40 to bedrawn back. The rod 6 is depressed until the catch 7 rests in the notch8 of the presser-foot and holds the roller 2 raised. The pile of paperis then placed upon the table 0 close against the front board 57, and bymeans of the set-screws 66 the crossbar 12 is adjusted over the backedge of the pile. By means of the set-screws 67 the sliding blocks :20are adjusted with the presserfeet over the back corners of the pile. Thebars 42 are then swung up and secured in position. By means of theset-screw 68 the holder 40 is adjusted over the back of the pile. Therollers 2 are dropped upon the top sheet, and the machine can then bestarted. Immediately or slightly prior to the commencement of theforward stroke the bar 0) commences to descend and the rollers 2 to bendorbuckle inward the back corners of the topmost sheet, and when thebar 1) has fully descended the resser-feet z are resting on the exposedcorners of the second sheet, and the rollers 2 are raised from thepaper, after which the bar 1; remains stationary for rather more thanhalf a revolution of the driving-shaft b. During the latter part of thedescent of the bar 12 the holder 40 has been raised, so that the backend of the topmost sheet has been freed. By this time the carrier-slides17 have reached the commencement of the dropped portion of the races 16and commence to fall until the rubber-covered roller 23 rests upon thefront part of the top sheet and draws the sheet forward with it,delivering it before completing the forward movement into the grip ofthe feed-rollers e, which have just commenced to rotate. At this timethe feeler 58 is held raised by a spring attached to the rockingshaft 1) and bearing against the under side of the lever 55 close to itsattachment to the feeler; also, the holder 40 has dropped onto the topof the second sheet immediately the first sheet has moved sufficientlyfar for the back edge of the top sheet to be clear of the dropped holder40. During the return of the sliding carriers 17 the roller 23 revolvesover the top sheet while in contact with it, but is raised from it asthe carriers 17 leave the dropped portion of the race, so that thecontinned feed of the feed-rollers is not hindered. As the slidingcarriers 17 approach the back position the rotation of the feed rollersstops, leaving the top sheet still covering the greater part of the pilewhen the feeler 58 descends. At the same time the cross bar 4) israised, lifting the presser-feet .e and drawing back the rollers 2nearer the back corners of the pile, and the holder 40 is dropped ontothe back edge of the second sheet. On reaching the end of the backstroke the cross-bar 0 again begins to descend and continues to do soduring the first part of the forward stroke, the rollers 2 buckling orbending the back edge of the second sheet, so as to expose the backcorners of the third sheet. When the sliding carriers 17 have advancedsufficiently,which is soon after the commencement of the forward stroke,the front edge of the strip 38 or the apex of the lifter 34 reaches andpasses beneath the center of the back edge of the top sheet, and in itsfurther advance gradually lifts the whole length of the back edge of thetop sheet, which slides up the incline of the lifter 34, and thus overthe top of the roller 23, which is still moving forward above and out ofcontact with the second sheet. When the carrying slides 17 thereforereach the dropped part of the races 16, the roller 23 descends onto thesecond sheet and draws it up into the grip of the feedrollers e, whichhave just commenced to revolve and which then carry forward both the topand second sheets together, but with the top sheet overlapping the frontedge of the second sheet a considerable distance. The other operationsare repeated as previously described, the drawing-roller 23, however,moving back between the top and second sheets until clear of theadvancing back edge of the top sheet, and the back edge of the secondsheet occupying when the feed-rollers stop the position previously heldby the edge of the top sheet. If the width of the sheets as measuredacross the feeder is considerable, two or more lifters 34: may be usedin place of one. The rod 35 is hinged in the hinged plate 36 to permitthe lifter 34 to be tilted over to the back of the roller or bar 23 wheninserting afresh pile; but this is not essential, as the rod 35 may beattached close to the back edge of the lifter 3a and hinged direct inthe back plates 19.

I am aware that prior to myinvention feeders for printing-machines havebeen made in which bending or buckling devices for separating one edgeof the topmost sheet and exposing part of the next sheet, pushing ordrawing rollers for pushing or drawing forward the separated sheets,automaticallylifted tables, and continuously or intermittently rotatedfeed-rollers have been used.

I do not therefore claim a combination of such broadly; but
